Scientists may be closing in on that mysterious substance called Dark Matter. A slew of new experiments and detectors are either operational or under construction to discover what makes up the unknown 80 percent of all the matter in the universe.
NASA's Fermi poised to pin down gravitational wave sources
Astronomers say they detected a sudden burst of Gamma Ray energy from the same region of space as the gravitational waves detected last September from a pair of merging black holes over a billion light years away. If confirmed, the would represent both the first evidence of electromagnetic radiation from the gravitational wave event, and also the first evidence contradicting existing hypothesis that black holes merge "cleanly," without producing any sort of light.
